Dr. Aurélien Drezet was born in Metz, France, in 1975. He received his Ph.D Degree in experimental physics from the University Joseph Fourier at Grenoble in 2002 where he was working on nano optics and near-field scanning optical microscopy. After 6 years as a post-doc in Austria and France, he is currently head of the Nano-Optics and Forces team at Institut Néel in Grenoble (which belongs to the national scientific research center-CNRS-France which is also associated with the University Joseph Fourier in Grenoble). His activities range from experimental and theoretical plasmonics to near-field scanning optical microscopy in both the classical and quantum regime. He is also strongly involved in scientific works and discussions concerning quantum foundations in general and Bohmian mechanics in particular.

This paper aims to present an analysis of the Pusey, Barrett and
Rudolph (PBR) theorem concerning ontic and epistemic hidden
variables in quantum mechanics. This is also a review and defense of my previous critical analysis done in the context of Bohmian mechanics and the occasion to review some of the fundamental aspects of Bohmian theory rarely discussed in the literature.
